Which action should be taken when a channel is overloaded?

• A. Switch to alternate channel or tiered communications as per policy, and establish a dedicated channel for incident command.
• B. Ignore and continue on current channel.
• C. Increase transmitter power.
• D. Broadcast only to field units.

Answer: (A)

When a channel is overloaded, the priority is to keep critical communications clear and reliable. Switching to an alternate channel or using tiered communications as the policy directs, and establishing a dedicated channel for incident command, ensures that command can coordinate effectively without being buried in congestion. This approach preserves a clear path for vital messages, maintains situational awareness at the incident command post, and uses available frequencies or channels in a structured way. Increasing transmitter power can cause interference and isn’t a guaranteed fix, while continuing on the same channel or limiting broadcasts to field units can leave the incident without cohesive command and risking missed information.
